Mandarin Duck Cave, Cangjun Cave Introduction
"Mandarin Duck Playing in Water - Mandarin Duck Cave" is located in the northeastern part of Wangan Island. It is a natural valley formed by topography, and it is said to have been named because of the presence of mandarin ducks playing and resting in the many water caves. Offshore, the saddle-shaped Saddle Mountain lies as a barrier. Therefore, during the Japanese occupation, the Japanese military established it as an important naval base, with the "Storage Cave" being a remaining historical site in the area. In 1944, the Japanese military enslaved the residents of Wangan and Jinmen Islands to excavate it, using it as a base for naval torpedo boats and as living quarters for special attack forces. Just as the construction was nearing completion, Japan announced its unconditional surrender, and the base was abandoned. Many caves have collapsed, but some remnants can still be vaguely seen.
